Homework Equations
##v=\omega r##
The Attempt at a Solution
So, using the equation, one can work out the velocity at point ##B##.
##v_B=\omega_{AB} \cdot r_B##
##v_B=6(0.4)=2.4~ ms^{-1}##I then tried working out the angular velocity at point ##C## using the instantaneous centre of zero velocity (I'm not sure of this is the correct next step. I don't think it is). But this ends up giving:
##\cos60= \frac {0.6} {r_{B/IC}}##
##r_{B/IC}=1.2##
Using ##v=\omega r##, this gives the angular velocity at point ##C## as ##2~rad/s##. This can't be right though since the velocity comes out as ##0.2## using ##r=0.1~m##
The answer is ##1.04~ms^{-1}##
